T o all whom it'fmvay concern:

Be it known that we,CHR1sTi-AN N. QLs'EN and AXEL P. PETERSEN, -citizensyof the United States, residing atJersey City, in thecounty of Hudsonand State of NeWJersey,

T e invention comprises the provision of a filtering medium andareceptacle for receiver ing dirt and extraneous matter and means forholding the filtering material and' recepta'cle in proper relations toeach other.

' The 'invention further comprises the pro'- vision of a'lteringdeviceformed of a plurality `of layersi of Wire netting arranged conesfor receiving and distributing the gas over the entire surface thereof,and a drip.

receptacle positioned for receiving dirt Aand other extraneous matterfrom' the strainer, y. together with connection adapted 'to fit anordinary gas pipe and at thesame time hold a receptacle and a filter inproper relation' to each other.

The object in view is the provision cfa ilterin medium arranged in theflow ofv gas A Whenv a ove a receptacle for receiving dirt.

Another object in view istheprovision of aV c onicallyshaped lter orstrainer arranged in the ath of the flow of gas for lseparating from t egas dirt and other extraneousmat'- ter contained therein, a receptaclepositioned in proximity to the strainer for'v receivingiiirt therefromand means vfor holding-the strainer and receptacle in proper relation toeach other.

L With these and other objects inf'vieW the invention comprises certainnovel constructions, combinations and arrangement of parts that Will behereinafter more fully described and claimed. e

In the accompanying drawings: Figurev 1 is a side'elevation of thepresent invention connected up ready for use. Fig-2 is alongitudinallyverticalsection through Fig. 1,'the valve being omitted. f

In manufacturing gas and distributing .the same to pipes or mainsvarious foreign substance or extraneous matter is mechanically suspendedin the "gas andhis delivered With such Aextraneous matter either ta thepipes or suspended in thcgas from any register in the meter pnly t l.various-meanshave been provided with varylis firmly secured to pipe 5genera ,desired may be simply forced' into pipe 5'and cylinders f -Wirenetting fitte the gas. I Also it `liasbeen found that .various'extraneous matter or `partielles taken lup by thefgas from thecorrosion of the pipe, and

en from other sourc'eggat ers momentum as the same are forced along'andwhen striking the meter near the. point of'vdestination will greatlyassist the gas in -operating the same. In order to therefore secure puregas and .to-

Y epassage of gas,

ing successes, and-it is to this class of devices that the presentinvention relates.

Referring 'more particularly .to the drawings f1 indicates the pipe ofany desired construction for containing gas and is designed ,tosupplythev gasmeterlnot shown) with gas in the usual manner through pipe'2.` Secured in pipe 1 is avalve 3 of any deslredconstructlonfor'letting ofl" the gas as may be desired.AConnectedto'pipe 1 is a T fitting 4 preferably of the' usualconstruction. e G0114v nected to iittingll is'af'short pipe 5 Whichinturn is connected to pipe 2 by means ofpnion 6.` Positioned in' ipe 5 isa lter'7 that' is formed with acy' ndricalportonf a held therebyfriction., As shown in the `drawings conical-.part 9 isfsoldered tocylinlsimply `mixing the'wires and twisting the u l.same after lmixingor interlocking. The conical'portionV 9 is formed of va (plurality of.'g'rilfltoqeach other; the outer vcone'being the largest land theinner'most' 'cone/the smaller, `so as to l form a plurality o? distinctcone-shaped sieves oriilters.arranged in succession against which thegask passing from pipe 1 to pipe 2 must impinge. yThe impingmg of agasagainst thefirst or outer cone will greatly clean the gas and remove amajor part of the dirt an'd other extraneous matter from lthe gas. LAsthe gas continues through' the cone- -shaped member 9 it Will befurther cleaned as it-kpasses through the res uective cones successivelyuntil it is almost a solutely' pure when it enters ipe 2.

Secured to 'tting or member 4 isa 'receptacle 1 1 that is preferablyremovably secured to member 4 as' by threads 12, Receptacle 10 may be ofany'desired'size and is provided with a-bottoln or cap 13 that isremovably secured in position preferably by threads 14..

The filter 7 is so arranged as to have the conical shaped members orportions 9 projecting toward the flow of gas and across the receptacle11 so that all the dirt and other matter may fall into -the receptaclethat is removed from the gas j It is to be observed that the filter orstrainer 7 will -not onlylterthe gas in the usual acceptation of theword but will also catch all solid .particles which are mechanicallysuspended in the gas so that the same are deosited in a res`evoir orreceptacle 11 and not orced through the meter, The forcing of l suchsolid particles through the meterhas a tendency to accelerate the speedof the meter and consequently register a greatervolume of gas thanactually passes through the meter. i 4 A 1 In forming the conical-shapedmember 9 the same may be formed of any'desired material as copper orbrass and in distinct cones and secured together by solder. However,under some circumstances I wind wire netting into a conical-shaped coiland then secure the same to cylinder 8.

is more quickly andy cheaply, constructed. When the strainer is full ofdirt or other eX- 4traneous matter the same maybe removed and cleaned inany desired Way and also the receptacle 11 may be cleaned by simplyremoving cap 13.

What I claim is: 1. .A strainer for'gas comprisinga casin a nettmg woundinto a plurality of convoIu- This willl give the same effect as distinctcones and tions, means for holding the same in position and a receptaclefor receiving extraneous matter therefrom. f

2. A strainer comprising a holder, a conical-shaped strainer formedfroma plurality of conical-shaped sieves telescoped into each otherandin contact their entire length, and

means for receiving dirt from said conicalshaped strainer.

3. A strainer, comprising a holder, a dirt receptacle and a strip ofnetting wound into a conical-shapedstrainer having a plurality oflayers, said strainer being in posltion above said receptacle forreceiving dirt and deposing the same in said receptacle. 1

4. A 4gas strainer comprisinga holder, a dirt receptacle, aconical-shaped strainer in position above said receptacle andconstruct-- j ed of a plurality of conical shaped s'trainers formed ofnetting and positioned in Contact lwith each other through their entirelength CHRISTIAN N.
